Dubsmash Wars: Melissa Benoist from 'Supergirl' enlisted by Team S.H.I.E.L.D.

For round 2 of the Dubsmash Wars for Charity, Team S.H.I.E.L.D.’s Clark Gregg and Chloe Bennet appear with Melissa Benoist, the star of CBS’ Supergirl. Also in attendance from the Marvel and DC camps are Deadpool and Batman, respectively, in cosplay. (No, that is not Ryan Reynolds behind that red mask.)

Their collaborative lip-sync to “Why Can’t We Be Friends” is a timely arrival to the Marvel vs. DC debate recently reignited by comments from Batman v Superman director Zack Snyder and Captain America’s Sebastian Stan.

Team Agent Carter‘s Hayley Atwell and James D’Arcy previously kicked off round 2 with a cameo from Marvel Comics creator Stan Lee. A get, to be sure, but no war-ending peace offering. What could possibly be in store for round 3?
